DETAILED DESCRIPTION OF EMBODIMENTS

In order to understand the above purposes, features, and advantage of the present disclosure more clearly, the technical solutions according to the present disclosure will be further described. It should be noted that the embodiments of the present disclosure and the features in the embodiments may be combined with each other if there is no conflict.

In the following description, numerous specific details are set forth in order to provide thorough understanding of the present disclosure. However, the present disclosure may also be implemented in other ways different from those described here. Obviously, the embodiments in the specification are only a part of the embodiments of the present disclosure, rather than all the embodiments.

With the diversification of video processing functions, the interactive functions on the video processing interface are inclined to become complicated, which causes inconveniences for users to operate during the video processing process, affecting the user experience in video processing.

In practical application scenarios, the video editing window can display more video editing functions through scrollbars. Nevertheless, scrolling based on scrollbars may cause the tracks (e.g., video tracks or audio tracks) used to assist users in video editing no longer be displayed in the video editing window, affecting the user experience in the video editing.

To this end, a video processing method is provided according to the present disclosure. In an embodiment, a mask layer is displayed at a bottom area of a video editing window, on detecting that an editing reference track of a to-be-processed video moves out of the video editing window. The editing reference track comprises a video track and/or an audio track. Then, the editing reference track of the to-be-processed video is displayed on the mask layer based on a timeline on the video editing window. The editing reference track displayed on the mask layer is configured to assist a user to edit the to-be-processed video in the video editing window.

It can be seen that in the video processing method provided according to the embodiments of the present disclosure, the editing reference track can be redisplayed by means of a mask layer when the editing reference track moves out of the video editing window, which can reduce the impact on the video processing of the user, thereby improving the user experience.

Based on this, a video processing method is provided according to an embodiment of the present disclosure. Referring to FIG. 1 , FIG. 1 is a flowchart of a video processing method according to an embodiment of the present disclosure, the video processing method includes steps S101 and S102 as follows.

In S101, on detecting that an editing reference track of a to-be-processed video moves out of a video editing window, a mask layer is displayed at a bottom area of the video editing window. The editing reference track includes a video track and/or an audio track.

The video processing method provided according to an embodiment of the present disclosure can be applied to functions such as video editing.

In practical applications, the video track and audio track play a certain auxiliary role in the video processing performed by the user. Hence, when the user is processing the to-be-processed video, the video track and audio track of the to-be-processed video should be displayed on the video editing window to enhance the user experience in video processing.

To this end, in the embodiments of the present disclosure, on detecting that the editing reference track of the to-be-processed video moves out of the video editing window, the editing reference track of the to-be-processed video moved out of the video editing window is displayed by means of a mask layer, so as to reduce the impact on the video processing of the user.

In a possible implementation, the user may need to scroll up and down the video editing window during video processing. When scrolling up and down, the editing reference track in the video editing window may move out of the video editing window, i.e., no longer appears in the video editing window. In order to reduce impact on the video processing of the user, in the embodiment of the present disclosure, a mask layer is displayed at the bottom area of the video editing window and the editing reference track is redisplayed on the mask layer.

The bottom area of the video editing window may be a display area determined based on the bottom boundary of the video editing window. The mask layer displayed in the bottom area has a certain degree of transparency, so as not to affect the content display and operation control in the underlying area covered by the mask layer while displaying the editing reference track on the mask layer. For example, the underlying area covered by the mask layer will update the display content as the video editing window is scrolled up and down.

In a possible implementation, on detecting that the video track of the to-be-processed video moves out of the video editing window, a mask layer is displayed at the bottom area of the video editing window. Alternatively, on detecting that the audio track of the to-be-processed video moves out of the video editing window, a mask layer is displayed at the bottom area of the video editing window. Or, on detecting that both the video track and audio track of the to-be-processed video move out of the video editing window, a mask layer is displayed at the bottom area of the video editing window. The video track may include a main video track, or the video track may include a main video track and a picture-in-picture track.

In S102, based on a timeline on the video editing window, the editing reference track of the to-be-processed video is displayed on the mask layer, where the editing reference track displayed on the mask layer is configured to assist a user to edit the to-be-processed video in the video editing window.

In the embodiment of the present disclosure, a timeline is displayed on the video editing window. Based on the timeline, the editing reference track of the to-be-processed video is displayed on the mask layer, so that the editing reference track displayed on the mask layer is consistent with the timeline displayed in the video editing window, which is convenient for the user to edit the to-be-processed video.

In a possible implementation, after the editing reference track is moved out of the video editing window, the editing reference track is always displayed on the mask layer at the bottom area of the video editing window, so as to facilitate the user to edit the video. On detecting that the editing reference track moved out of the video editing window moves back into the video editing window, the mask layer and the editing reference track displayed on the mask layer can be hidden to avoid redundant display of the editing reference track. At this point, the user can edit the to-be-processed video based on the editing reference track moved back into the video editing window.

In the video processing method provided by the embodiments of the present disclosure, on detecting that an editing reference track of the to-be-processed video moves out of the video editing window, a mask layer is displayed at the bottom area of the video editing window, where the editing reference track includes the video track and/or audio track. Then, based on the timeline on the video editing window, the editing reference track of the to-be-processed video is displayed on the mask layer. The editing reference track displayed on the mask layer is used to assist the user to edit the to-be-processed video in the video editing window. It can be seen that the video processing method provided according to the embodiments of the present disclosure can redisplay the editing reference track by means of a mask layer when the editing reference track moves out of the video editing window, which can reduce the impact on the video processing of the user, thereby improving the user experience.

In practical applications, in a case that the editing reference track includes an audio track, the audio track of the to-be-processed video can be displayed on the mask layer in a preset manner.

In a possible implementation, the audio track of the to-be-processed video can be displayed in the form of a visual line. For example, a time point where target audio data is located in the audio track of the to-be-processed video is determined. And a target audio visual line is then generated for the audio track of the to-be-processed video based on the time point where the target audio data is located. The target audio visual line is used to visualize a playback position of the target audio data in the to-be-processed video. In other words, through the target audio visual line, it can be determined where the target audio data is located in the to-be-processed video, for example, the playback position of the background music in the to-be-processed video can be determined.

As shown in FIG. 2 , FIG. 2 is a schematic effect diagram of a video editing window according to an embodiment of the present disclosure. A mask layer is displayed at the bottom area of the video editing window, and a video track and a target audio visual line are simultaneously displayed on the mask layer. The target audio visual line may include at least one line segment, and the video track may include a main video track and a picture-in-picture track.

It is apparent that, in some implementations, only the video track may be displayed on the mask layer at the bottom area of the video editing window. Alternatively, only the target audio visual line may be displayed, which is not limited in this embodiment of the present disclosure.

In addition, the target audio data in the embodiments of the present disclosure may include audio data of music type, and/or audio data of sound effect type.

In an embodiment, the audio data of the music type is usually electronic music, such as songs, light music, etc. In the embodiment of the present disclosure, the determining a time point where target audio data is located in the audio track of the to-be-processed video can include: determining a time point where the audio data of the music type is located in the audio track of the to-be-processed video. The audio track can include at least one audio track of the music type.

The audio data of the sound effect type is usually special effect audio, dubbing, text reading and the like, such as the special effect audio “meow-” similar to cat meowing. In the embodiment of the present disclosure, the determining a time point where target audio data is located in the audio track of the to-be-processed video can include: determining a time point where the audio data of the sound effect type is located in the audio track of the to-be-processed video. The audio track can include at least one audio track of the sound effect type.

In a possible implementation, in a case that there is only one audio track including target audio data in the to-be-processed video, the time point where the target audio data is located in the audio track is determined as the time point where target audio data is located in the audio track of the to-be-processed video.

In another possible implementation, in a case that there are at least two audio tracks including the target audio data in the to-be-processed video, which are referred to as a first audio track and a second audio track in the following description as an example, then the determining a time point where target audio data is located in the audio track of the to-be-processed video can further include the following steps.

First, a time point where target audio data is located in the first audio track and a time point where target audio data is located in the second audio track are determined respectively. Then, the time point where target audio data is located in the first audio track and the time point where target audio data is located in the second audio track are combined to obtain a combined time point. Based on the combined time point, the target audio visual line for the to-be-processed video is generated.

As shown in FIG. 3 , FIG. 3 is a schematic diagram showing that time points of target audio data on multiple audio tracks are combined according to an embodiment of the present disclosure. The first audio track includes audio data A and audio data B, and the second audio track includes audio data C. Based on the timeline, the time points corresponding to audio data A, audio data B, and audio data C respectively are combined to obtain the combined time point, that is, the time point where the audio data A, audio data B, or audio data C is located. The time points corresponding to the audio data A, the audio data B and the audio data C are combined. In an embodiment, the time point where at least one of the audio data A, the audio data B and the audio data C is located in the to-be-processed video is reserved to form the target audio visual line.

In a possible implementation, the target audio data can include audio data of the music type and audio data of the sound effect type. Hence, in the embodiments of the present disclosure, visual line for the audio data of the music type and visual line for the audio data of the sound effect type can be generated separately. In an embodiment, based on the time point where the audio data of the music type is located in the audio track of the to-be-processed video, the music audio visual line is generated. At the same time, based on the time point where the audio data of the sound effect type is located in the audio track of the to-be-processed video, the sound effect audio visual line is generated.

FIG. 4 is a schematic effect diagram of a video editing window according to another embodiment of the present disclosure. On the mask layer of the video editing window, the main video track, the picture-in-picture track, the audio visual line L1 of the music type, and the audio visual line L2 of the sound effect type are displayed based on the same timeline.

In the video processing method provided according to the embodiments of the present disclosure, the time point where the target audio data is located in the audio track may be displayed for the user in the form of visual line, thereby optimizing the display effect of the video editing window without affecting the video processing, which is convenient for the user to operate, thereby improving the user experience.

In practical applications, in the process of video processing, the beat-tracking point is an important reference factor. Therefore, in the embodiment of the present disclosure, before displaying the target audio visual line on the mask layer based on the timeline on the video editing window, it is necessary to determine the beat-tracking points of the to-be-processed video, and then the beat-tracking points can be displayed to facilitate the video processing of the user and improve the user experience.

In an embodiment, in a case that the target audio data is audio data of the music type, the beat-tracking point is determined from the time point where the target audio data is located in the audio track of the to-be-processed video, and then the beat-tracking point is marked on the audio visual line of the music type.

The beat-tracking point is used to identify the rhythm, melody and the like of the music. The beat-tracking point can be automatically generated in advance or manually determined by the user, which is not limited here.

In a possible implementation, in a case that there is only one audio track including the audio data of the music type in the to-be-processed video, the beat-tracking point(s) on the audio track is determined as the beat-tracking point(s) of the to-be-processed video.

In another possible implementation, in a case that there are at least two audio tracks including the audio data of music type in the to-be-processed video, which are referred to as a third audio track and a fourth audio track in the following description as an example, then the beat-tracking points on the third audio track and the fourth audio track are superposed based on the timeline to determine the beat-tracking points in the to-be-processed video. As shown in FIG. 4 , beat-tracking points are marked on the audio track of the music type.

In the video processing method provided by the embodiments of the present disclosure, not only the target audio visual line is displayed for the user on the mask layer, but also the beat-tracking point is displayed for the user, which can optimize the display effect of the video editing window without affecting the video processing, which is convenient for the user to operate, thereby improving the user experience.
